Bradley McDougald is staying in Seattle.

The versatile Seahawks safety, who was scheduled to become an unrestricted free agent Wednesday, has agreed a three-year extension. The deal is worth $13.95 million, according to NFL Network's Mike Garafolo.

The Seahawks will keep one of their own free agents. They’ve agreed to terms on a three-year, $13.95 million deal with S Bradley McDougald, source says. He stepped into a starting role last year when Kam Chancellor went down. Chancellor’s future remains murky.

McDougald, who signed a one-year, $2 million deal with Seattle in 2017 and appeared in all 16 games last season, making nine starts in place of Earl Thomas (two games) and Kam Chancellor (seven games).

Re-signing McDougald, 27, solidifies the safety spot regardless of what happens with Chancellor, whose future remains uncertain due to a season-ending neck injury suffered in November. If Chancellor's career is over, then McDougald would serve as a relatively inexpensive replacement, who is already familiar with the system.

According to Pro Football Focus, McDougald was one of the best safeties in the league against the run in 2017, recording 17 run stops through week 16. McDougald seemed to be more than capable in pass coverage as well, showing an ability to protect passes over the top of the defense and defend tight ends.

There has been much speculation that perhaps Seattle will draft safety Derwin James in the first round as a potential replacement for Chancellor, but for now the team's starting strong safety is McDougald.
